PVP Industries Horticultural Coarse Vermiculite, Natural and Odorless Mix - Professional Use for Gardening, Packaging, and Industrial, 4 Cubic Feet

Unlock the natural power of vermiculite, an incredibly versatile, lightweight mineral used across horticulture, construction, environmental cleanup, and more. This all-purpose product is permanent, odorless, sterile, and incredibly durable; it won’t deteriorate over time, making it a go-to choice for both professionals and DIYers. In horticultural applications, vermiculite excels as a growing medium. Known for its unique "wicking" properties, it naturally attracts and holds essential nutrients such as ammonium, potassium, calcium, and magnesium, helping to support faster root development and stronger plant growth. Mix it with soil, peat, composted pine bark, or fertilizers to improve aeration and moisture retention. Ideal for seed germination, cutting propagation, and passive hydroponic systems, vermiculite soaks up over three times its volume in water, reducing plant maintenance and improving yield. Vermiculite’s usefulness extends well beyond the garden. In construction, it serves as a key ingredient in fireproof cements, insulations, and lightweight concretes, perfect for use in ovens, fireplaces, and industrial applications. It’s widely used in vinyl pool base cements, battery shipments, brake linings, and hazardous material packaging due to its insulating and adsorbent properties. Whether you're growing healthy plants or building fire-safe structures, this all-in-one mineral solution is an essential addition to your toolkit.
